Is There Any Danger When the Charger Makes Abnormal Noises?

[LaRachel]

It is normal for the charger to make abnormal noises, and there is no danger. The charger contains a fuse. If the temperature or voltage is too high, the electronic tube may burn out, but it will not explode. The sound from the charger could also be the noise of the current during charging. If the noise is too loud, you can replace it with a charger of the same model. More details about car chargers are as follows: Correct Charging Methods: Do not charge immediately after riding. The lifespan of lithium-ion batteries is determined by the number of charge-discharge cycles. The more charge-discharge cycles, the faster the lifespan decreases. Therefore, you should not charge the electric vehicle every time after riding. Instead, charge it when the battery reaches 60%-70% of its maximum range. It is best to use a smart socket. Many electric vehicle users charge their vehicles when they get home from work and unplug the charger when they leave for work the next day. However, most chargers cannot guarantee 100% automatic power-off when the battery is fully charged. The best solution is to purchase a smart socket and set the charging time, which can address the issue of resting peacefully at night. Be cautious of plug overheating during charging. Loose 220V power plugs or charger output plugs, as well as oxidized contact surfaces, can cause the plug to overheat. Prolonged overheating may lead to short circuits or poor contact, damaging both the charger and the battery. Therefore, be vigilant about plug overheating during charging. If this occurs, promptly remove the oxides or replace the connector. Charging during the day is safer. When charging a newly purchased electric vehicle for the first time, the battery should be fully charged. However, full charge and overcharging are entirely different. Electric vehicles have relatively standard indicator lights, and different models and battery standards may prompt the dealer to provide different suggestions. At the same time, charging during the day makes it easier to control the charging time and reduces the risk of battery-related safety issues such as fires. Solutions for Abnormal Noises: The solution for a charger making a squeaking noise during charging is to use a syringe to apply a small amount of engine oil or other lubricant to the fan shaft, which should resolve the issue.
